OLED-Info: the OLED experts

OLED-Info has been the leading international OLED publication for over 10 years, with a readership of more than 120,000 professionals a month. We provide a multitude of services to the OLED market based on our extensive and up-to-date knowledge hub and close ties with industry leaders. Our consultancy services include market outreach assistance, display brokerage, business development, financial intermediation and more.

An OLED uses organic semiconductors to create thin light emitting panels. OLEDs are used to create thin, beautiful, flexible and efficient display and lighting panels, and are the future technology of choice.

The Brite 3 OLEDs are more efficient than OLEDWorks' current Brite 2 OLEDs, offering an efficiency of up to 85 lm/W. The brightness is 300 lumens (8,500 cd/m2) and the lifetime is 100,000 hours (L70, at 100 lumens). The Brite 3 OLEDs are available in two colors and offer a CRI of >90. The Brite 3 are offered in three product shapes: square, rectangle and round. These Lumiblade panels will be produced at OLEDWorks' Aachen production site.

One of these reports came from Taiwan's Digitimes, but a new report from Digitimes suggests that Apple does plan to upgrade its OLED iPhone X in 2018. According to Digitimes, Apple will introduce a slightly larger 5.9" OLED model. In total Apple will buy 110-130 OLED panels in 2018, for all three OLED models (the 2017 iPhone X, the 2018 5.9" iPhone XI and the larger 6.5" OLED iPhone XI plus).

Bloomberg posted an interesting article, saying that Apple is making good progress in its Micro-LED development project, and has managed to produce promising display samples. Apple is seeking to use Micro-LED displays in future wearable products - and eventually use Micro-LEDs in smartphones and maybe VR HMDs as well.

Apple is not likely to become a MicroLED producer, but it does seek to control the production process entirely - and so become the first (and only) company to be able to adopt these displays.

Tianma demonstrated its flexible and foldable AMOLED displays at MWC 2018 earlier a couple of weeks ago, and the following video shows a nice tour of the displays at Tianma's booth.

The first display you see is a 5.5" FHD flexible AMOLED (on a Polyimide substrate). There's a long discussion there about creating a foldable Phone around that, but beyond that it is nice to see Tianma's flexible OLEDs in action.

To achieve such high transparency, AUO optimized the TFT array layer stack, the OLED cathode pattern and the encapsulation. This is the first transparent OLED AUO has developed since 2011. It will discuss this new display at SID Display 2018 - and will hopefully demonstrate it as well.

Visionox developed a 7.2" foldable AMOLED display, and has tested its reliability. Visionox says that even after 200,000 folding cycles, the display still showed good reliability. Visionox also performed extensive surface hardness and ball/pen drop tests on this display.

Visionox will discuss the reliability and failure mode analysis of its foldable OLEDs at SID Displayweek 2018 in May - and will also hopefully demonstrate this new display. Visionox performed the tests on a display module that included the AMOLED panel, a touch layer and a thin circular polarizer layer.

In a very natural move, LGD announced today that it will bring the Crystal Sound technology to its OLED lighting panels as well. LGD will unveil the first OLED lighting speakers at the Light and Building tradeshow next week in Germany. You can see a couple of such lighting speaker designs above.
